[aw] Smoke Claude on Copilot hit HTTP 400 bad request

[github-actions]

Workflow Failure

Workflow: Smoke Claude on Copilot
Branch: copilot/fix-claude-configuration
Run: https://github.com/github/gh-aw/actions/runs/29526411109
Pull Request: #46013

Warning

HTTP 400 Bad Request from agentic engine: The agent failed after the engine returned Response status code does not indicate success: 400 (Bad Request).

This is usually a request validation failure rather than a timeout or quota issue.

How to debug this

1. Inspect the run's agent-stdio.log and safeoutputs.jsonl artifacts around the first HTTP 400.
2. Check for malformed request data, invalid tool-call payloads, or stale conversation state being replayed.
3. If the failure happened on a resumed session, rerun fresh once to confirm whether persisted state is corrupt.

Warning

Engine Failure: The claude engine terminated unexpectedly.
